Need FBW idle training(tune included)
Would anyone like to offer help on this tune. he is a It has a tr220 550 lift cam and 3k stall. The truck stalls at red lights and takes some gas pedal work to get an idle after starting. Suggestions on what to change, thread links, pid list, and any helpful post as always are much appreciated.

Notice too that the maf is disabled. Runs much worse with the maf on. The tune is mostly an old sd tune that was for the 4.8 with the cam, but the owner says it died some back then as well.

While it is about the E38 & idle a lot of the information will be relative to what you are trying to achieve.

b3701 seems incorrect for 36lbs injectors ,eg at 13.5v at around idle (75 -65) you have .124ms very low figures my 42lbs have a coil saturation lag of .745ms that's prob why you have high ve numbers between 80-100kpa you r not giving your injectors time to open
Thanks for looking. My Z has 36lb injectors. The tune you are looking at is for a 04 c1500 with a 5.3(tr220) swap was a 4.8. It has 42lb injectors. I increased the desired airflow at idle in drive and in park and my buudy is no longer two footing it, but it still needs some fine tuning. Thanks...
